Abstract: The apparatus has an X-ray source (3) having an electron source (31) and a stationary anode (4) which describes a full or partial anode ring with a circuit for accelerating electrons emitted from the electron source, using a high positive constant voltage, towards the anode ring. The electrons form an electron beam (32) which collides with the anode ring at a focal spot (41) which, in turn, emits X-ray radiation in the form of a fan beam (42). With a full or partial X-ray detector ring (5) the detector ring and the anode ring are coaxially arranged and define a scan slice. The detector ring is such as to permit the spatial resolution around the ring of the X-rays detected. A number of electron sources are arranged on an electron source ring (33) in proximity to the anode ring. A circuit is provided to control the sources individually in order to emit electron beams in set time sequence. The focal spots produced by the electron beams on the anode ring are each electromagnetically swept over a portion of the anode ring.

Granted: 1985-10-14
Abstract: The illumination arrangement has an optical prism for separation of flat incident light beam into its basic colours for obtaining a curved light band. The light can be projected to a wall or ceiling. The flat light beam emerges from a slot which faces the prism (14). The prism can be adjusted about its longitudinal axis arranged parallel to the edges of the prism. Hence the inclination of the prism walls relative to the flat light beam can be varied. This prism can have a non polished base surface.

Abstract: A method of manufacturing hollow needles from round metal blanks in order to form a needle which has an inner front portion with a front end tapering to a point and a rear portion having a larger diameter than the front portion and forming a mounting shank, comprising forming a longitudinally extending needle guide to the needle such that the guide is open at the rear end of the mounting shank and tapers from a substantially uniform depth along a major portion of its length to a minimum depth adjacent the tip. The channel is of a shape to receive substantially cylindrical cross pins having an appended piece of filament which form a part of fasteners for tags, buttons and similar items to be attached to carrier materials such as textiles. The method is carried out by the use of a disc-shaped miller cutter which has U-shaped convex teeth for milling the central area of the channel in side tooth portions for milling shoulders on each side of the channel which are of lesser depth than the channel. The side tooth portions are employed to mill inclined V-recessed surfaces on each side of the central channel. In accordance with the inventive method after the channel is milled it goes to extend from the rear end along the inner front portion and taper to substantially a minimum depth at a spaced location from the tip, a stamping tool is used to engage into the inclined surfaces formed by the side teeth so that these surfaces are pressed inwardly to close a major portion of the length of the channel but without closing a release portion adjacent the tip of the needle which is less substantially equal to the width of the channel.

Abstract: A method and apparatus provide for the continuous digestion of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, with increased sulfidity. When black liquor is withdrawn from the continuous digester (32), instead of merely passing it to a pair of flash tanks (25, 26) and then to recovery, the concentrated liquor from a first flash tank is fed to a vessel (15) in which the comminuted material is slurried with a liquid. Since the black liquor remains in intimate contact with the chips for a significant period of time, the lignin in the chips is partly sulfonized. Ultimately the black liquor is replaced with white liquor or the like, and the separated out black liquor is circulated to recovery or disposal. A high pressure feeder (16) and a solids/liquid separator (36) are utilized.

In a stable, some air is extracted and some recirculated by a fan unit loacted in a vent pipe in the roof of the stable. The fan unit comprises a fan 11 within a duct 28 and below a duct 8 which is located within the vent pipe (not shown). Part of the air withdrawn from the stable flows axially upwardly into the vent pipe and part is deflected by a baffle 24 to return radially into the room. In an alternative embodiment two fans are employed, one axial fan within the duct 8 and one centrifugal fan below the duct 8, which fans may be driven independently by thermostatically controlled motors. Air may be let into the room by means of up-turned inlet pipes (7, Fig. 1) or by means of an annular passage 33 around the duct 8. The rate of outflow of air is controlled by simultaneously operable dampers 13, which are lifted by the air flow to an extent which is controlled manually (Fig. 2) or by a thermostatically controlled servomotor 39. The rate of in-flow of air may be controlled by a slidable duct length 34 which protrudes beyond the inner end of the annular passage 33.

Title: Improved display device
Inventor: GROSSE MAURICE
IPC: G09F11/32
Filed: 1988-04-14
Abstract: Display device comprising shaped guide plates (44) positively guiding the suspension rods (4) of viewing sheets (3) around a roller (8) when each suspension rod (4) is engaged by cradles (11) carried by electrically driven chains (10). A strap (50) which is rendered resilient by the inclusion therein of a spring (53) extends centrally down the rear of the device and prevents the successive suspension rods (4) from becoming detached from the cradles (11) in this region. A gate which includes a stop (55) is provided at the foot of ramps (5) upon which the rods (4) are stacked to ensure that the rods will not become bunched or otherwise entangled on the ramps (5) and that the cradles (11) will positively pick up only one suspension rod (4) at each passage past the gate. A time delay switch (56) is associated with a microswitch (41) and will close to bypass switch (41), after a predetemined interval of time, so that the drive of the device may re-start even if the power supply to the device had previously been switched off with the microswitch (41) in its open circuit position. Each rectangular display sheet (3) preferably comprises two layers which are secured to one another at the edges which coincide with the suspension rods (4) and along one of two longitudinal edges. The other edge is open except for two relatively short portions that are joined together at its opposite ends, whereby webs carrying indicia may be entered between the layers, by appropriate flexing, and will remain trapped therebetween by the short joined together edge portions of the two layers.
